CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia[1] and infection of any site.[2] The CURB-65 is based on the earlier CURB score[3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia.[4]
The score is an acronym for each of the risk factors measured. Each risk factor scores one point, for a maximum score of 5:
- Confusion of new onset (defined as an AMT of 8 or less)
- Urea greater than 7 mmol/l (19 mg/dL)
- Respiratory rate of 30 breaths per minute or greater
- Blood pressure less than 90 mmHg systolic or diastolic blood pressure 60 mmHg or less
- age 65 or older

Predicting death [edit]
Pneumonia [edit]
The risk of death at 30 days increases as the score increases:[1]
- 0—0.7%
- 1—3.2%
- 2—13.0%
- 3—17.0%
- 4—41.5%
- 5—57.0%
The CURB-65 has been compared to the pneumonia severity index in predicting mortality from pneumonia.[5] It was shown that the PSI has a higher discriminatory power for short-term mortality, and thus is more accurate for low risk patients than the CURB-65 or its predecessor, the CURB score.[3]
It is used as a means of deciding the action that is needed to be taken for that patient.
- 0-1: Treat as an outpatient
- 2-3: Consider a short stay in hospital or watch very closely as an outpatient
- 4-5: Requires hospitalization with consideration as to whether they need to be in the intensive care unit
Any infection [edit]
Patients with any type of infection (half of the patients had pneumonia), the risk of death increases as the score increases[2]:
- 0 to 1 <5% mortality
- 2 to 3 < 10% mortality
- 4 to 5 15-30% mortality
